(the reasons why show effect)
<Dispersibility improves effect>
Used in the present invention, polyurethane dispersant (b-1) is characterised by comprising the part-structure shown in above-mentioned formula (i).
It is believed that by comprising the part-structure shown in above-mentioned formula (i), can be by solvophilic group or adsorption group, especially contain
The part-structure of solvophilic group or the part-structure containing adsorption group configure on straight line such that it is able to improve the phase to solvent
Dissolubility and the adsorptivity to pigment entirety.Furthermore it is possible to think that the nitrogen-atoms in amino-formate bond position are also beneficial to face
The absorption of material, based on the synergy with adsorption group, can make pigment adsorption become good further.
Particularly, make solvophilic group be comprise polyether chain and/or the group of polyester chain in the case of, exist and following incline
To:Its by this position with photosensitive polymer combination in solvent (e) affine thus stretching in a solvent, thus in pigment
In the case of being intended to during dispersion condense, space bit resistance part can be become and given play to the function of preventing pigment from cohesion occurring.
In addition, if so that after in the polarity of polyether chain and polyester chain and solvent polarity or photosensitive polymer combination
The mode that the polarity of the alkali soluble resin (d) of narration or photopolymerization monomer is consistent is constituted, then there are following tendencies:Chain part
It is susceptible in a solvent stretch and so that sterically hindered effect is increased, so that dispersibility becomes good.
In particular it is preferred that comprising the solvophilic group with polyether chain and both solvophilic groups with polyester chain.
It is believed that by having both, there are following tendencies:It is easily tailored as making the polarity with solvent for the polarity of solvophilic group
It is consistent, solvophilic group stretches in a solvent further, sterically hindered effect increases further, better dispersed can be obtained
State, even if also can stably keep dispersity after passing through for a long time.
Further, preferably adsorption group and main chain polyurethane skeleton away from.By making specific adsorption group and master
Chain polyurethane skeleton away from, exist during pigment adsorption sterically hindered diminish, tendency that pigment adsorption improves further.
<Process patience and raising thermostability and form high fine fine rule by improving alkali development>
By using the photosensitive polymer combination containing polyurethane dispersant (b-1), flat board can be applied to by manufacture
Even if the fine light filter of computer or fine display etc. and make particularly through the work of alkali development or high-temperature process
Also fine high fine rule can be stably formed in sequence.
In order to be stably formed fine fine rule, need to make this narrow line shape be stably formed in alkali development, and make
Even if in its curing process based on more than 200 DEG C of high-temperature heating treatment behind, thermal deformation is also less, stably keeping should
Shape.
It is believed that due to pigment and dispersion for the photosensitive polymer combination containing polyurethane dispersant (b-1)
The absorption affinity of agent is strong, thus high with respect to the patience of alkaline developer, therefore, is temporarily forming during alkali development after uv irradiation
Even if fine fine rule in the case of being impregnated in alkaline developer further, also can suppress developer solution in this fine rule
Being impregnated with of the part closely sealed with substrate, can prevent embedded generation, the generation peeled off, the deformation of cone-shaped being caused by etch.
Furthermore it is possible to think, even if in the case of carrying out high-temperature process in more than 200 DEG C after development and so that it is solidified, pigment with point
The absorption of powder also will not weaken, and thermal deformation is few, therefore can stably keep fine narrow line shape.

Effect, can reach on a small quantity what highly sensitive oxime ester Photoepolymerizationinitiater initiater (c-1) and polyurethane dispersant (b-1) were applied in combination
In the case of, the crosslinking irradiated based on ultraviolet of photopolymerization monomer or alkali soluble resin can be promoted, they and poly- ammonia can be made
Mutual winding between the solvophilic group of ester dispersant becomes more strong, thus resistance to alkali-developable and thermostability can be improved,
Fine narrow line shape can be stably formed.
Particularly, be used the resin comprising more aromatic ring as alkali soluble resin in the case of, there are following tendencies:
High-fire resistance and high alkali resistance can be obtained based on this aromatic ring, in addition, sterically hindered also can improve based on larger in three-dimensional
Thermostability and alkali resistance are such that it is able to form fine narrow line shape more stablely.
In addition, in the case of using opacifiers such as white carbon blacks, when its average primary particle diameter is less, this polyurethane dispersant
(b-1) it is easier capture pigment, thus resistance to alkali-developable and thermostability improve further, can be formed fine more stablely
Narrow line shape.
Polyurethane dispersant (b-1) comprise to have polyether chain solvophilic group and have polyester chain solvophilic group this
In the case of both, there are following tendencies:They are easily handed over high molecular alkali soluble resin or by ultraviolet
The photopolymerization monomer of connection is compatible it is easier to mutual be wound around, therefore with respect to the patience of alkaline developer and with respect to high temperature at
The patience of reason improves.
In addition, further, in the case that polyether chain has the alkylidene oxide of long-chain, gather with alkali soluble resin or light
Conjunction property monomer is compatible further, becomes easily mutually to be wound around, and alkali resistance and thermostability improve, and are therefore more highly preferred to.
Additionally, it is preferred that the polyurethane skeleton of adsorption group and main chain away from.By making the poly- ammonia of adsorption group and main chain
Away from there are following tendencies in ester skeleton:This adsorption group be adsorbed in during pigment sterically hindered diminish, polyurethane dispersant
(b-1) become easily to capture pigment, its patience with respect to alkaline developer and the patience with respect to high-temperature process increase further
Plus.

Difference.
In addition, in the case that the acidic-group of alkali soluble resin is carboxyl, dispersion will not be impacted, with dispersant
(b) affine weaker, there is the etch that can suppress to be caused by alkaline developer further in alkali development or high temperature behind
By the tendency of thermally-induced deformation during reason.
Further, in the case that alkali soluble resin has ethylenically unsaturated group, there are following tendencies:By ultraviolet
Irradiate and crosslink, so that the polyether chain of above-mentioned polyurethane dispersant (b-1) and/or polyester chain and alkali soluble resin
D the mutual winding between () becomes more strong, the alkaline developer patience of ultraviolet irradiation portion and thermostability become very large.
In addition, in the case that alkali soluble resin (d) has ethylenically unsaturated group, being applied in combination polyurethane dispersant
(b-1) improve further with the effect brought of oxime ester Photoepolymerizationinitiater initiater (c-1).
Particularly, ultraviolet be difficult to the substrate and thread pattern arriving at bonding portion or in ultraviolet exposure due to
The presence of mask and lead to ultraviolet to be blocked thus the side surface part of thread pattern that weakens, by having olefinic unsaturated group
The alkali soluble resin of group is applied in combination with polyurethane dispersant (b-1) and oxime ester Photoepolymerizationinitiater initiater (c-1), exists and can assist
Improve together alkaline developer patience and thermostability, thus easily forming the tendency of high fine fine rule.
In addition, being used epoxy (methyl) acrylate solvable as the alkali with carboxyl and ethylenically unsaturated group
In the case of property resin, more addition unsaturated group or carboxyl can be made in resin.In addition, aromatic ring can more be imported

Table 8
As shown in table 8, as the embodiment containing dispersant 1 and the photosensitive polymer combination of oxime ester Photoepolymerizationinitiater initiater
5 μm of fine rules after 1 development, relatively thin compared with 6 μm of fine rules, therefore affected be more susceptible to alkaline developer or heat treatment, meeting
More or less observe the symptom of a trend that rectilinearity reduces, live width can slightly broaden 0.1 μm or cone angle slightly reduces 5 degree, but still be able to good
Form well 4.6~5.5 μm of 5 μm of fine rules.
In addition, embodiment 6 is because the primary particle diameter of pigment is less, be 23nm, surface area is big, it is understood that dispersion
Agent is easily adsorbed at pigment, with this concomitantly, is adsorbed in the solvophilic group of the dispersant of pigment and alkali soluble resin can have
Imitate compatible, as a result, in the same manner as when 6 μm of fine rules, rectilinearity and embedded 5 μm of good fine rules can be formed.
Used in the resist of the present embodiment, polyurethane dispersant, by combining with alkali soluble resin, can make dispersant
Solvophilic group and alkali soluble resin compatible well, thus forming good space bit resistance part, viscosity and OD are all good,
And dispersibility is also good.
In addition, in an embodiment, employ, in 1 intramolecular, there is ultra-violet absorption position, energy transmission position and freedom
The oxime ester Photoepolymerizationinitiater initiater of base generating unit, thus, even if be difficult near the substrate closed surface that arrives in ultraviolet it is also possible to
Alkali soluble resin etc. is made effectively to be polymerized.It is believed that thus, alkali soluble resin can be made molten with the parent of polyurethane dispersant
Mutual winding between agent portion is more strong, though in the solidification irradiated based on ultraviolet it is also possible to suppression pigment cohesion,
Thus keeping good dispersity, as a result, can make equably to show in fine rule from the resistance to alkali-developable of pigment and resistance to
Hot, thus obtaining the fine rule that rectilinearity is good, embedded and etch of based on alkaline developer is few.
Further, since used in embodiment 1,2,3 dispersant all pendant types of adsorption group, therefore can recognize
For, can improve with the absorption affinity of pigment, reduce amount of free dispersant.It is believed that thus, in heat treatment, free dispersant
Can play a role as grease such that it is able to prevent cone angle from declining, live width increases.
On the other hand, the photosensitive polymer combination of comparative example 9 passes through mainly there is free radical generating unit
IRG907 initiator and mainly have the DETXS initiator at ultra-violet absorption position and be applied in combination to produce free radical, can recognize
For due to employing 2 kinds of Photoepolymerizationinitiater initiaters, therefore free radical generation efficiency is poor, waits purple particularly near substrate closed surface
The part that outside line is difficult to arrive at is difficult to be polymerized, and with this concomitantly, leads to create thermal deformation in heat treatment.
In addition, employing the comparative example 1 of the dispersant 5 without adsorption group and employing as polyurethane skeleton
The comparative example 4,5 and 6 of the dispersant of graft polymers in addition, the in the resist dispersion of pigment weak with the absorption affinity of pigment
Property is insufficient.
It is understood that when manufacturing light filter, pigment and the combination of dispersant in heat treatment can be led to die down, send out
The cohesion of raw pigment is it is impossible to fully show resistance to alkali-developable and thermostability from pigment it may occur that thermal deformation.
In addition, employing the comparative example 2 and 3 of the commercially available dispersant with amino-formate bond, due to being by having 3
The polymer by several toluene di-isocyanate(TDI)s of above isocyanates links the skeleton that links of group and several through skeleton
Solvophilic group or the dispersant of adsorption group composition, the building-up effect accordingly, with respect to pigment is low, and, due to also can produce
Life is sterically hindered with respect to adsorption group, therefore low to the absorption property of pigment.Additionally, the amount of solvophilic group and absorption base
The amount of group is all few than polyurethane dispersant used in embodiment, thus is believed that solvophilic group and alkali soluble resin
Between compatible insufficient, occur pigment cohesion it is impossible to fully show the resistance to alkali-developable from pigment and thermostability.
Additionally, employing the comparative example 7 and 8 of acrylic compounds AB block dispersant, because adsorption group collects in dispersion
The side of agent, it is understood that pigment adsorption group can produce sterically hindered to each other and cannot fully be adsorbed in pigment,
Amount of free dispersant is led to increase.It is understood that the substrate that cannot obtain by dispersant between pigment and substrate is closely sealed
Power, alkali development patience is low it is difficult to realization patterns.
Using specific embodiment, the present invention is described in detail, but those skilled in the art should understand that
It is without departing from the spirit and scope in the present invention, various changes can be carried out and revise.It should be noted that this
Apply for that the Japanese patent application (Japanese Patent Application 2014-143279) being proposed based on July 11st, 2014 is completed, entire contents
