An organopolysiloxane fine particle comprising as a principal component a polysiloxane having a hydrocarbon group (a) directly bonded to a silicon atom and having an OH group (b) directly bonded to a silicon atom, wherein: (i) carbons contained in the hydrocarbon group (a) constitute 5 to 35% of the weight of the organopolysiloxane fine particles, and (ii) the OH group (b) is in an amount of 1 to 8 meq per g of the organopolysiloxane fine particles, the organopolysiloxane fine particles having: (iii) a 10% compressive modulus of elasticity of 150 to 900 Kg/mm2, (iv) an average compressive deformation (Cr)m of 20 to 60%, (v) an average elastic recovery (Rr)m of 60 to 90%, and (vi) an average particle diameter of 0.5 to 50 &mgr;m. With respect to this organopolysiloxane fine particle, besides the requirements (i) to (vi), it is preferred that the statistical dispersion of the 10% compressive modulus of elasticity of the organopolysiloxane fine particle fall in the range ±20% based on an average of the 10% compressive modulus of elasticity. The produced organopolysiloxane fine particle exhibits a low aggregation ratio and an extremely sharp particle diameter distribution. The compressive modulus of elasticity, elastic recovery and compressive deformation thereof are high, and the statistical dispersion of compressive deformation is small. Moreover, the organopolysiloxane fine particle is excellent in the spreadabillty on a base. Therefore, the organopolysiloxane fine particles are suitable for use as a spacer fine particle to be incorporated in, for example, a liquid crystal cell.
摘要:
The present invention relates to spherical laminated particles each comprising a core particle and a laminate part disposed on a surface of the core particle, wherein the laminate part has a compressive modulus which is smaller than that of the core particle. These spherical laminated particles have a large compressive strength and is excellent in the recovery from a deformation by an arbitrary load, when the load is removed afterwward, as compared with conventional elastic particles composed of a single substance. Therefore, the use of these spherical laminated particles as spacers minimizes the difference in extent of displacement of spacer particles attributed to the difference in load on individual spacer particles caused by, for example, the waviness of a substrate for liquid crystal display cell during the manufacturing of the liquid crystal display cell, so that the cell gap uniformity can be ensured.
