Abstract
A film-forming composition containing a polymer obtained by polymerizing (A) 5 to 80 mass % of a silicone resin having an RSiOunit, an RR'SiOunit, and an SiOunit, where R may be the same or different and represents a monovalent hydrocarbon group having 1 to 6 carbon atoms, and R′ represents a —CHSH group, wherein a total amount of the RSiOunit, RR′SiOunit, and SiOunit is 80 mol % or more with respect to all structural units, and a mole ratio expressed by (sum of RSiOunit and RR′SiOunit)/(SiOunit) ranges from 0.5 to 1.5 and (B) 20 to 95 mass % of one or more radically polymerizable compounds, wherein component (B) includes (B-1) one or more radically polymerizable monomers having no SiO unit in a structure thereof. This composition is capable of forming a transparent film that is excellent in adhesiveness without exhibiting stickiness and secondary adhesion.
