Coating composition, adhesive or non-adhesive coating layer containing said coating composition, and laminate including these coating layers

Abstract

Coating compositions including 0.5 to 30.0% by mass of acrylic polymers (A) and 70.0 to 99.5% by mass of polymerizable compounds (B) are provided. The acrylic polymers (A) contain a branched alkyl group having 3 to 20 carbon atoms and/or a branched or unbranched alkenyl group having 3 to 20 carbon atoms in the side chain. The coating compositions can form non-adhesive coating layers with good adhesion to various resinous base materials excellent surface hardness, tack resistance, bending resistance, scratch resistance, shrinkage resistance and moisture heat resistance. The coating compositions also can form adhesive coating layers with excellent close adhesion, adhesiveness, transparency, contamination resistance, heat and moisture resistance, yellowing resistance, and step followability. Moreover, various laminates, cover films, cover substrates and the like having these coating layers on one side or both sides of the resin films and/or resinous base materials are provided.
