Latest Patents

Sekiguchi holds a patent for a hard coat film and the method for producing it. The invention provides a hard coat film that exhibits excellent adhesion to a hard coat layer when a cycloolefin polymer film is utilized as a base material. The hard coat film comprises a hard coat layer containing an ionizing radiation curable resin, which is laminated on at least one surface of a cycloolefin polymer base film through a primer layer. This primer layer is composed of a modified polyolefin resin, which is graft-modified with an α,β-unsaturated carboxylic acid or a derivative thereof, along with a (meth)acrylic acid ester. The graft weight of the α,β-unsaturated carboxylic acid or derivative is specified to be between 0.4 to 7 wt. % when the amount of the modified polyolefin resin is considered as 100 wt. %.
