Abstract
The present invention relates to a photo-dimerization functional group-containing organopolysiloxane represented by the following formula (1): (R3SiO1/2)m (R2SiO2/2)n (RSiO3/2)p (SiO4/2)q (1) wherein, R are each independently selected from the group consisting of monovalent hydrocarbon groups, alkoxy groups having 1 to 6 carbon atoms, photo-dimerization functional groups, and hydroxyl groups, provided that an average of at least three R in a molecule are the photo-dimerization functional groups; and m, n, p, and q are each numbers greater than or equal to 0, and satisfy the following condition: 3.0≦m+n≦20,000. The photo-dimerization functional group-containing organopolysiloxane cures rapidly due to irradiation by activation energy radiation such as ultraviolet radiation or the like.
