Abstract:
A combination for surface treating powder, composed of (I)organopolysiloxane or condensate thereof and (II)organopolysiloxane in a weight ratio of (I):(II) of from 95:5 to 5:95; (I)organopolysiloxane or condensate thereof and (III) acryl/silicone copolymer in a weight ratio of (I):(III) of from 95:5 to 5:95; or (I)organopolysiloxane or condensate thereof, (II)organopolysiloxane and (III) acryl/silicone copolymer in a weight ratio of (I):[(II)+(III)] of from 95:5 to 5:95, provided that each of (I), (II), and (III) may be packed together or separately, wherein (I)organopolysiloxane is represented by the following formula (1),
R 1 a (OR 2 ) b SiO (4-a-b)/2 (1)
wherein R 1 may be the same with or different from each other and is a C 1-30 alkyl, aryl, aralkyl, fluorinated alkyl or amino-substituted alkyl group, R 2 is a C 1-6 alkyl group, a is the number of from 0.75 to 1.5, and b is the number of from 0.2 to 3, provided that a sum of a and b is greater than 0.9 and at most 4; (II)organopolysiloxane is represented by the formula (2)
R 3 c R 4 d R 5 e SiO (4-c-d-e)/2 (2)
wherein R 3 may be the same with or different from each other and is a C 1-30 alkyl, aryl, aralkyl, or fluorinated alkyl group,
R 4 is a hydrogen atom, a hydroxyl group or a C 1-6 alkoxy group and is bonded to the Si atom in the formula (2) via a group comprising carbon, oxygen, or silicon atom, and
R 5 is a silicone compound residue represented by the following formula
wherein R3 is as defined above, c is the number of from 1.0 to 2.5, d is the number of from 0.001 to 1.5, and e is the number of from 0 to 1.5, x is an integer of from 1 to 5, and y is an integer of from 0 to 500; and
