Abstract
Abstract The production of polymeric bodies having included, isolated areas of fine metal or metal oxide particles dispersed therein by mixing a metal compound with a polymer, converting the resulting mixture to a desired shape and irradiating selected areas of the shape with laser light to decompose the metal compound in the irradiated areas.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
96 words
The method for producing polymeric bodies made of a light-transmitting polymer having at predetermined locations therein fine opaque metal or metal oxide particles which comprises providing a shaped polymeric body having substantially uniformly distributed therethrough a metal-organic compound selected from the group consisting of carbonyls, bis-cyclopentadienyls, arenes, mixed arenes, arene-carbonyl complexes and ferrocene and irradiating with laser light selected areas of said shaped polymeric body, said laser light irradiation acting within said selected areas to decompose at least a portion of said metal-organic compound to provide in said irradiated areas opaque metal or metal oxide particles.
