Abstract
The problem of the present invention is to provide the reduction for not only suppressing the initial performance when hot and humid lower long-time is used but also can meet the easy adhesive composition of humidity resistance under more harsh environment and the optical film of the adhesive layer formed by the easy adhesive composition is set at least one surface of thermoplastic resin film.The present invention provides a kind of easy adhesive composition, and it contains:100 parts by weight have the water-dispersible polyurethane resin of carboxyl, 1~25 parts by weight water-soluble carbodiimide compound and 1~25 parts by weight water dispersible carbodiimide compound;A kind of optical film, it is that the adhesive layer formed by the easy adhesive composition is set at least one surface of thermoplastic resin film.
Description
Technical field
The present invention relates to easy adhesive composition and the optical film with the adhesive layer being made up of the easy adhesive composition.
The invention further relates to the manufacture method of the optical film and possesses the polarizer (polarizing plate, Polarizer) of the optical film
And image display device.
Background technology
The acrylic acid series tree that known (methyl) acrylic polymer by by representative of polymethyl methacrylate is formed
The optical characteristics such as adipose membrane light transmittance are excellent, and mechanical strength and shaping processability is harmonious excellent.Therefore, acrylic acid series tree
Adipose membrane has been applied to be assembled in liquid crystal display device (LCD), plasma display panel (PDP), organic EL display
(OLED) optical film of image display device as.
Optical film in the state of the stacking of other functional membranes generally with using.For example, regarding optical film as polaroid
(polarizer) diaphragm is in use, at least one side of polaroid can be laminated in via hydrophilic adhesive layer.Obtain
The polarizer can be used for image display device etc..In this case, the adaptation of optical film and polaroid is well important.
However, for acrylic resin film, it is poor with the cementability of hydrophilic adhesive to exist, close with polaroid
The problem of conjunction property is insufficient such.Therefore, it is proposed to be set on the surface of acrylic resin film with polyester, acrylic acid tree
Fat, polyurethane etc. help the resin of cementability for the adhesive layer of main component, assign easy-adhesion to acrylic resin film
Method.
On the other hand, in recent years, used carrying equipment of the image display devices such as LCD etc. whether indoor or
Used in outdoor various environment, even sometimes requiring that the humidity resistance that hot and humid environment is also resistant to.For being used for
The polarizer of such purposes, it is desirable to also do not occur the high adhesion of splitting under hot and humid.
Therefore, in Japanese Unexamined Patent Publication 2009-193061 publications, as the polarizer of the excellent adhesion under hot and humid,

Embodiment
[easy adhesive composition]
The easy adhesive composition of the present invention contains:Water-dispersible polyurethane resin with carboxyl (is hereinafter sometimes referred to simply as U trees
Fat) and it is sub- as the water-soluble carbodiimide compound (hereinafter sometimes referred to simply as S compounds) and water dispersible carbon two of crosslinking agent
Amines (hereinafter sometimes referred to simply as D compounds).The easy adhesive composition constituted as described above not only suppresses high in high temperature
The reduction of initial performance when wet lower long-time is used, and under more harsh environment, adaptation is also excellent.
For the existing known adhesive layer for the purposes, in hot and humid lower long-time in use, closely sealed
The reduction of property can not be avoided.However, in the present invention, suppress the reduction of the initial performance when hot and humid lower long-time is used,
Excellent adhesion under hot and humid.Though its reason is indefinite, it is presumed as follows:S compounds are from D compounds respectively different
Period forms cross-linked structure, in the following manner function.
That is, S compounds and the compatibility of other hydrophilic resins is good, and cross-linking reaction speed is fast, therefore in adhesive layer
During formation, or earlier stage after its formation, the carboxyl formation cross-linked structure with U resins.On the other hand, D compounds and S chemical combination
Thing is compared, and cross-linking reaction speed is slow, therefore, when adhesive layer is formed, the D compounds of remained unreacted in adhesive layer.
Under hot and humid, when the U resins in adhesive layer are Polyester, polyester is hydrolyzed, and ester bond is cut off, and produces carboxylic acid group.
Herein, it is believed that unreacted D compounds are reacted with the carboxylic acid group produced and form cross-linked structure, will be because easy to stick caused by hydrolysis
The deterioration selfreparing of layer is connect, thus, the strength deterioration of the adhesive layer under suppression is hot and humid.
In addition, there is also the functional groups such as carboxyl in the functional layer or thermoplastic resin film for be laminated in adhesive layer.Recognize
