These monomers may be used singly or in combination of two or more in view of difficulty in using a single compound in the production process. If necessary, a polyfunctional monomer having no acid group and a polyfunctional monomer having an acid group may be used in combination as a monomer.

The preferable acid value of the polyfunctional monomer having an acid group is 0.1 mg KOH / g to 40 mg KOH / g, particularly preferably 5 mg KOH / g to 30 mg KOH / g.

The details of the structure, the use of the single polymerizable compound, the combination thereof, and the amount of the polymerizable compound can be arbitrarily set in accordance with the final performance design of the coloring composition. For example, from the viewpoint of sensitivity, a structure having a large amount of unsaturated groups per molecule is preferable, and in many cases, a bifunctionality or more is preferable. Further, from the viewpoint of enhancing the strength of the cured film formed by the coloring composition, it is preferable to use trifunctional or more functional groups and the number of functional groups different from each other (e.g., acrylic acid ester, methacrylic acid ester, styrene series compound, vinyl ether group compound) A method of controlling both sensitivity and strength is also effective. It is also preferable to use a polymerizable compound having three or more functional groups and having different ethylene oxide chain lengths from the viewpoint that the developability of the colored composition can be controlled and an excellent pattern forming ability can be obtained.

The compatibility and dispersibility with other components (for example, photopolymerization initiator, dispersant, alkali-soluble resin, etc.) contained in the coloring composition is also an important factor for selecting and using the polymerizable compound.

The polyfunctional thiol may be added for the purpose of improving stability, odor, resolution, developability and adhesion.

The coloring composition of the present invention preferably contains a photopolymerization initiator from the viewpoint of further improving the sensitivity.

The photopolymerization initiator is not particularly limited as long as the photopolymerization initiator has the ability to initiate polymerization of the polymerizable compound, and can be appropriately selected from known photopolymerization initiators. For example, it is preferable to have photosensitivity to a visible ray from an ultraviolet ray region. In addition, it may be an activator that generates an active radical by generating some action with a photoexcited sensitizer, or may be an initiator that initiates cationic polymerization depending on the type of the monomer.

It is also preferable that the photopolymerization initiator contains at least one compound having a molecular extinction coefficient of at least about 50 within a range of about 300 nm to 800 nm (more preferably 330 nm to 500 nm).

Particularly, when the coloring composition of the present invention is used in the production of a color filter provided in a solid-state image pickup device, it is necessary to form a fine pattern in a sharp shape, and therefore it is important that the coloring composition is developed with no caking Do. From this viewpoint, it is particularly preferable to use an oxime compound as the polymerization initiator. Particularly, in the case of forming a fine pattern in a solid-state image pickup device, stepper exposure is used for curing exposure. Since this exposure device may be damaged by halogen, and the addition amount of the polymerization initiator should also be suppressed to a low level, Taking this into consideration, it is particularly preferable to use an oxime compound as a photopolymerization initiator in order to form a fine pattern such as a solid-state imaging element.

4. Fabrication of Color Filter by Coloring Composition

&Lt; Pattern formation >

Each of the coloring compositions of the prepared examples and comparative examples was coated on the undercoat layer of the silicon wafer substrate with the undercoat layer obtained in the above 2 to form a colored composition layer (coating film). Then, a heat treatment (prebaking) was performed for 120 seconds using a hot plate at 100 캜 so that the dried film thickness of the coated film became 0.6 탆.

Subsequently, the pattern was exposed at a wavelength of 365 nm at various exposure amounts of 50 to 1200 mJ / cm ² through an Island pattern mask having a square of 1.0 탆 square using an i-line stepper exposure apparatus FPA-3000i5 + (manufactured by Canon Inc.).

Thereafter, the silicon wafer substrate on which the irradiated coated film was formed was placed on a horizontal rotary table of a spin shower developing machine (DW-30 type, manufactured by KEMITRONICS Co., Ltd.), and a CD-2000 (FUJIFILM ELECTRONIC MATERIALS Ltd.) for 60 seconds at 23 占 폚 to form a colored pattern on a silicon wafer substrate.

The silicon wafer on which the colored pattern was formed was fixed to the horizontal rotary table by a vacuum chucking method and the silicon wafer substrate was rotated at a rotation speed of 50 rpm by a rotary device, To perform a rinsing treatment, and thereafter spray-dried.

Thus, a monochromatic color filter having a coloring pattern formed by the coloring composition of Example or Comparative Example was produced.

Thereafter, the size of the colored pattern was measured using a measurement SEM "S-9260A" (manufactured by Hitachi High-Technologies Corporation). The exposure amount at which the pattern size becomes 1.0 mu m was defined as the optimum exposure amount.

5. Performance evaluation

5-1. Light resistance

- Fabrication of monochromatic color filters and evaluation of light resistance -

Each of the colored curable compositions obtained above was coated on a glass substrate using a spin coater so that the film thickness after drying was 0.6 占 퐉 and prebaked at 100 占 폚 for 120 seconds to obtain a monochromatic color filter for light resistance evaluation.

The resulting monochromatic color filter for evaluating light fastness was irradiated with a xenon lamp at 100,000 lux for 20 hours (equivalent to 2,000,000 lux · h). The color difference (? E * ab value) of the monochromatic color filter before and after the xenon lamp irradiation was measured and used as an index of light fastness. When the value of? E * ab is small, the light resistance is good.

5-2. Heat resistance

The glass substrate coated with the obtained coloring composition was placed on a hot plate at 200 캜 so as to be in contact with the substrate surface and heated for 1 hour and then subjected to color difference measurement with a color meter MCPD-1000 (manufactured by Otsuka Denshi Co., Ltd.) (? E * ab value) was measured and evaluated as an index for evaluating the fastness to heat (heat fastness). The value of? E * ab indicates that the smaller the value, the better the heat resistance. The value of? E * ab is a value obtained from the following color difference formula by the spatial colorimetric system of CIE 1976 (L *, a *, b *) (Japanese Society of Color Science, New Color Science Handbook .266).

ΔE * ab = {(ΔL * ) 2 + (Δa *) 2 + (Δb *) 2} 1/2

The evaluation criteria are as follows.

-Evaluation standard-

A: No coating irregularity was confirmed at all.

B: Some coating irregularity was confirmed.

C: Many coating irregularities were confirmed.

5-4. Developability

The number of the incompletely developed portions was counted by observing 100 portions removed with a developing solution of a colored pattern using a cross-section SEM " S-4800 " (manufactured by Hitachi High-Technologies Corporation). The smaller the number, the better the developability.

5-5. Solvent resistance

The colored curable compositions of the examples and comparative examples obtained above were applied to a glass wafer using a spin coater so as to have a thickness of 0.6 mu m after drying and heated for 300 seconds on a 200 DEG C hot plate.

Propylene glycol monomethyl ether acetate (PGMEA) was added dropwise to the color filter obtained above, left for 120 seconds, and rinsed with running water for 10 seconds.

The spectral fluctuation of the transmittance before and after dropping the various liquids was measured using MCPD-3000 (manufactured by Otsuka Denshi Co., Ltd.), and the color difference? Eab was measured. The lower the? Eab, the better the solvent resistance.

[Table 2]

As is apparent from the above table, when a color filter is produced by using a photoresist using the composition of the present invention, a composition excellent in light resistance, heat resistance, coating property and solvent resistance can be obtained. It was also excellent in developability. Particularly, it has been found that the dye having a nitroxide having a triisocyanate and a t-butyl group as a terminal group exhibits particularly excellent performance.
