An ornamental article comprising a natural ornamental material such as pearl and a cured coating membrane of a composition based on organic materials which is coated on the surface of said natural ornamental material in a thickness from 0.01 .mu.m to 30 .mu.m, with improved properties such as surface luster and resistivity to scratch, light, chemicals, etc.

Ornamental articles having coating membrane

Polyester compositions suitable for fiber and film formation contain from 0.2 to 3.0% by weight of fine particles of uniform size and possess sufficient slippery tendency, appropriate opacity and crystallizing potential; said particles containing lithium and phosphorus as a lithium salt of a phosphoric acid ester constituent of short chain polyesters.

Fiber and film forming polyester composition

A polyester filament in which a polyether-polyester block copolymer is dispersed as fine striae along the filament axis, at least one of which is substantially endless. Process for preparing the same includes a melt spinning apparatus with static mixing elements interposed between separate molten polymer feed passageways and spinneret holes.

Polyester filament having excellent antistatic properties and process
