A polarizing film, comprising a polarizer, and a transparent protective film laminated on/over at least one surface of the polarizer to interpose an adhesive layer between the surface and the transparent protective film, and the polarizing film comprising, on/over the adhesion surface of the polarizer, an adhesion-improving layer interposed between the polarizer and the adhesive layer. The adhesion-improving layer preferably comprises a compound represented by the following general formula (1): wherein X is a functional group containing a reactive group, and Rand Reach independently represent a hydrogen atom, or an aliphatic hydrocarbon group, aryl group or heterocyclic group that may have a substituent, and the compound represented by the general formula (1) is interposed between the polarizer and the adhesive layer.

Polarizing film, method for producing same, optical film, image display device, and adhesion improvement-treated polarizer

An organic metal compound-containing composition, comprising: at least one organic metal compound (A) selected from the group consisting of metal alkoxides and metal chelates, and a polymerizable compound (B) having a polymerizable functional group and a carboxyl group.

Organic metal compound-containing composition

A curable resin composition for forming an adhesive layer on at least one surface of a substrate (C), the curable resin composition comprising: wherein X represents a functional group containing a reactive group, and Rand Reach independently represent a hydrogen atom or an optionally substituted, aliphatic hydrocarbon, aryl, or heterocyclic group; and

Curable resin composition, polarizing film and method for manufacture thereof, optical film, and image display device

In a method for manufacturing a polarizing film comprising a polarizer, a first transparent protective film provided on one surface of the polarizer with an adhesive layer interposed therebetween, and a second transparent protective film provided on another surface of the polarizer with an adhesive layer interposed therebetween, the adhesive layers are obtained by first using active energy rays to carry out irradiation by way of the first transparent protective film and then using the active energy rays to carry out irradiation by way of the second transparent protective film to cure the active energy ray-curable adhesive composition.

Polarizing film, method for manufacture thereof, optical film, and image display device

The present invention provides a polarizer protective film capable of suppressing blocking that occurs in taking up the film. The polarizer protective film of the present invention includes a (meth)acrylic resin film and an easy-adhesion layer formed of an easy-adhesive composition including a urethane resin and fine particles. The fine particles include preferably colloidal silica.

Polarizer-protecting film comprising an easy-adhesion layer composition, and polarizing plate and image display apparatus each comprising the polarizing-protecting film

The present invention provides a polarizing plate excellent in adherence (particularly, under high-temperature and high-humidity conditions) between a polarizer and a protective film. The polarizing plate of the present invention includes: a polarizer; an adhesive layer; an easy-adhesion layer formed of an easy-adhesive composition containing a urethane resin having a carboxyl group and a cross-linking agent; and a protective film containing a (meth)acrylic resin.
