Latest Patents
Among Yoshida's latest patents is the invention of a hard coat film and the method for producing it. This innovative hard coat film boasts excellent adhesion to a hard coat layer when a cycloolefin polymer film is employed as a base material. The patent details a hard coat layer that consists of an ionizing radiation curable resin, laminated on at least one surface of a cycloolefin polymer base film through a specialized primer layer. This primer features a modified polyolefin resin, which is graft-modified with an α,β-unsaturated carboxylic acid or a derivative, along with a (meth)acrylic acid ester. Notably, the graft weight of the α,β-unsaturated carboxylic acid or derivative is kept within 0.4 to 7 wt. % relative to the total weight of the modified polyolefin resin.
Another notable aspect of this hard coat film is its prime layer's arithmetic average surface roughness, which ranges from 0.5 nm to 15.0 nm. The surface of this primer layer displays a static friction coefficient ranging from 0.6 to 2.0, granting it superior performance attributes.
