Abstract: A (co)polymer(A)-acrylic block copolymer obtainable by reacting reactants comprising an acrylic material with a (co)polymer(A) is disclosed. The (co)polymer(A) comprises a substantially terminal ethylenically unsaturated functional group. The acrylic material is reacted with the (co)polymer(A) so that the acrylic material bonds to the (co)polymer(A) via the substantially terminal ethylenically unsaturated functional group. The disclosure extends to a coating composition comprising the block copolymer; articles, such as a package, packaging, a vehicle, a structure, or parts thereof coated with the coating composition; and methods of making the same.

Abstract: There has been a demand for an optical film having excellent glass-range photoelastic coefficient and a polarizing plate which uses this optical film. The present invention provides an optical film which is characterized by containing an ester-based resin that contains 50% by mole or more of a fumaric acid ester residue unit represented by formula (1) and having a negative birefringence, and a photoelasticity regulator having a positive birefringence, and which is also characterized in that the absolute value of the glass-range photoelastic coefficient thereof is 5×10−12 Pa−1 or less. (In the formula, each of R1 and R2 independently represents a linear alkyl group having 1 to 12 carbon atoms, a branched alkyl group having 3 to 12 carbon atoms, or a cyclic alkyl group having 3 to 6 carbon atoms.)
