To obtain the subject compound having a specific functional group, having ≤80°C glass transition temperature after crosslinking and slightly having an uncrosslinked extractable component.
This organopolysiloxane has at least one group represented by formula I [Z is CH2, chemical bond or the like; A is 1,4-phenylene or the like; M is a chemical bond, O atom or the like; VN is COO-CH=CH2 or the like; E is the group (CH2)r [(r) is 0 or an integer of 1-10]; (p) is an integer of 3-6; (q) and (s) are each 0 or 1; (t) is 0 or an integer of 1-3; (a) is 0 or an integer of 1-6] and, as necessary, has a group represented by formula III [(m) is same as (p); (n) is same as (q); X is cholesteryl or the like; Q is COO, O or the like]. The organosiloxane has liquid crystallinity. Thereby, an organosiloxane material having low glass transition temperature, especially a liquid crystalline pigment can be provided and the liquid crystalline pigment exhibits same reflection wavelength after processing even at remarkably different processing temperatures.
