The present invention relates to laser-markable polymers and coatings which are distinguished by the fact that they comprise tin/antimony oxide-coated spherical TiOparticles of defined particle size as laser additive.

Laser-markable polymers and coatings

The present invention relates to laser-markable and laser-weldable polymeric materials which are distinguished by the fact that they comprise, as laser absorber, at least one copper-doped zinc sulfide.

Laser-markable and laser-weldable polymeric materials

The present invention relates to an LDS-active additive for LDS plastics, to a polymer composition comprising an additive of this type, and to an article having metallized conductor tracks in which a polymeric basic body of the article or a polymeric coating on a basic body comprises an LDS additive of the said type.

Additive for LDS plastics

The present invention relates to laser-weldable polymers which consist of a laser-transparent part and a laser-absorbent part and can be welded to one another by means of laser light and are distinguished by the fact that the laser-absorbent part comprises, as absorber, copper hydroxide phosphate and/or copper phosphate.

Laser-weldable polymers

The invention relates to an infrared-reflective material which comprises a transparent sheet material which comprises, on a part-area, an interference pigment which has higher transmission in the visible region of global radiation than in the NIR region, to a method for screening an enclosed area against infrared light, and to the use of the infrared-reflective material for buildings, vehicles and greenhouses while simultaneously maintaining the ability of the human eye to see through the material.
