Abstract

Abstract of the disclosure The invnetion relates to a composite particle comprising 2 to 98% by weight of a base resin having a softending point of -10° to 120°C and a number average molecular weight of 600 or more and 98 to 2% by weight of an anisotropic crystalline polymer having a phase transition point of 60°
to 230°C and a number average molecular weight of 600 to 10,000 and capable of forming an anisotropic molten phase, the polymner having the specific structure in which a repeating unit of the formula: A-X-B (I) (wherein 100 to 50 mol % of A stands for defined mesogenic group, 0 to 50 mole % of A is p-phenylene, m-phenylene or trans-1,4-cyclohexylene, B is a defined spacer group, and X is ester bond, carbonate bond, amide bond, urethane bond or urea bond, and a repeating unit of the formula: R (II) in which R stands for bivalent to hexavalent hydrocarbon residue, are connected , in any successive orders and in a weight ratio of (I)/(II)= 99.9/0.1 to 60/40, with each other through ester bond, carbonate bond, amide bond, urethane bond or urea bond, and end portions are occupied by a functional group as hydroxyl , carboxyl and the like.
The composite particle is useful as powder coating , dry toner and the like.
