The present invention addresses the problem of providing: a peelable coating composition for which peeling due to light impact or scratch after drying is effectively prevented while peeling easily in operations in which peeling is intended; and a coating film obtained by drying said composition. The problem is solved by an easy peel coating composition comprising a polycarbonate resin with structural units represented by general formula (1): (1) and a non-halogen-based organic solvent, wherein the content of the polycarbonate resin in the composition is 0.1-50 mass % and the proportion of structural units represented by general formula (2): (2) in the structural units represented by general formula (1) is 0-80% as a mole ratio. ##STR00001##

Ways of preparing a partially crystalline polycarbonate powder are provided that include dissolving an amorphous polycarbonate in a polar aprotic solvent to form a first solution of solubilized polycarbonate at a first temperature. The first solution is then cooled to a second temperature, the second temperature being lower than the first temperature, where a portion of the solubilized polycarbonate precipitates from the first solution to form a second solution including the partially crystalline polycarbonate powder. Certain partially crystalline polycarbonate powders resulting from such methods are particularly useful in additive manufacturing processes, including powder bed fusion processes.

Di(amido(alkyl)phenol) compounds and upgraded molecular weight polymers made from such compounds have particular utility in coating compositions, especially for use on food and beverage contact substrates that are formed into or will be formed into containers or container components.
