Document Type and Number:

Japanese Patent JP5133060

Kind Code:

B2

Abstract:

Laser markable moding mass (I) comprises partly crystalline thermoplast (A), particular light sensitive salt like compound (A1) and/or particular inorganic oxide (A2) with average particle diameter of less than 250 nm and optionally further conventional additives (A3). Laser markable moding mass (I) comprises partly crystalline thermoplast (A), particular light sensitive salt like compound (A1), that under the influence of laser light changes its color or leads to the color change of plastic and contains several cation of titanium, chromium, manganese, iron, cobalt, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, gold, tin, antimony, lanthanide, praseodymium, tantalum, tungsten or cerium and further groups of element of 3-6 period of III and IV main group, 5-6 period of V main group and 4-5 period of III-IV next group and the lanthanide and/or particular inorganic oxide (A2) with average particle diameter of less than 250 nm and optionally further conventional additives (A3). Independent claims are also included for: (1) a method for laser marking of thermoplastic molded parts comprising preparing molded parts from (I) and illuminating pre-determined parts at the surface of the molded part with laser light to cause change in the optical appearance around the illuminated areas; (2) molded parts obtained by molding (I) by the above method; and (3) laser markable molded parts obtained by illuminating the molded parts from (I) with laser light.
