摘要：
Provided is a resin-linear organopolysiloxane block copolymer which has a high degree of freedom in formulation due to excellent compatibility with other materials, in addition to exhibiting excellent film forming properties and followability of a film, while the stickiness of a film is suppressed. The resin-linear organopolysiloxane block copolymer has: a resin structure (A1) block that has siloxane units represented by R1SiO3/2 (wherein R1 represents a monovalent organic group, a hydroxyl group, or an alkoxy group having 1 to 6 carbon atoms) and SiO4/2； and a linear structure (A2) block represented by (R2SiO2/2)n (wherein n represents a number of 5 or more while R represents an alkyl group, a fluoroalkyl group, or an aryl group) in each molecule. The resin structure (A1) and the linear structure (A2) are linked to each other by an Si—；O—；Si bond, and an Si atom bonded to the resin structure (A1) constitutes an RSiO3/2 unit.
