There is provided an optical film including an acrylic film, and a functional coating layer formed on at least one side of the acrylic film. The functional coating layer includes a water-dispersible resin and at least two kinds of fine particles having different average particle sizes.

Optical film including functional coating layer, and polarizing plate and image display apparatus including the same

The present invention relates to an optical film including: a base material film; and a primer layer containing a polyester resin and water-dispersible minute particulates on at least one surface of the base material film and having a refractive index difference of 0.03 or less from the base material film, in which the polyester resin includes polyester glycol formed by a reaction of polybasic acid including an aromatic carboxylic acid compound and an aliphatic carboxylic acid compound at a mole ratio of 1:9 to 9:1 and polyol, adhesion force between the optical film and a functional coating layer is excellent, and a rainbow phenomenon is reduced and an optical property is excellent due to a small refractive index difference.

Optical film comprising primer layer containing polyester resin and polarizing plate using same

The present invention relates to an optical film including an acryl-based film; and a functional coating layer formed on at least one surface of the acryl-based film, containing a conductive material and a water-dispersible resin and having surface resistance of 10W/Sq to 10W/Sq.

Optical film including functional coating layer and polarizing plate and image display device including same

A double-sided polarizer includes a polarizing film, a first adhesive layer formed on one surface of the polarizing film, a second adhesive layer formed on the other surface of the polarizing film, a first transparent film formed on the first adhesive layer, and a second transparent film formed on the second adhesive layer, wherein the first adhesive layer and the second adhesive layer are formed of an active energy line-curable adhesive and the first adhesive layer is 0.1 &#x3bc;m to 3 &#x3bc;m thick, and there is also provided an optical device including the double-sided polarizer.

Polarizer having protection films in two sides and optical device comprising the same

The present invention relates to an adhesive composition including 100 parts by weight of a first epoxy compound having a glass transition temperature of a homopolymer of not less than 120&#xb0; C., 30 parts by weight to 100 parts by weight of a second epoxy compound having a glass transition temperature of a homopolymer of not more than 60&#xb0; C., and 0.5 parts by weight to 20 parts by weight of a cationic photopolymerization initiator, and a polarizing plate using the same.

Adhesive for polarizing plate and polarizing plate including the same

The present invention relates to a protective film including: a transparent film, a coating layer formed on one surface of the transparent film, and a primer layer formed on the other surface of the transparent film, wherein the coating layer is formed using a coating composition including a first polymer resin, a first cross-linking agent and first water dispersible particles, and the primer layer is formed using a primer composition including a second polymer resin and second water dispersible particles, as well as including a second cross-linking agent in an amount, including 0% by weight, and lower than that of the first cross-linking agent, and a polarizing plate including the same.

Protective film and polarizing plate including the same

The present disclosure relates to a polarizing plate including: a polarizer; an acrylic film attached to at least one surface of the polarizer via an adhesive layer; and a primer layer formed on at least one surface of the acrylic film, wherein the primer layer is formed of a primer composition including a water dispersible resin containing a sulfonic acid group, water dispersible particles, and water, and a weight ratio of the water dispersible resin to the water dispersible particles is in a range of 1:0.01 to 5:1.

Polarizing plate

There is provided a polyester-based primer composition including 100 parts by weight of a polyester resin, 1 to 20 parts by weight of water-dispersible particles, and water as a remainder. Since a polyester-based primer composition of the present disclosure is excellent in water resistance and solvent resistance differently from a urethane primer composition, the polyester-based primer composition may obtain sufficient adhesive strength between a protection film and a functional coating layer even without assistance from additives such as a cross-linking agent, and may retain stable adhesive strength for a long period of time.
