摘要:
The present invention relates to a process for the production of a pattern having a three-dimensional appearance in a coating comprising flake-form effect pigments, to a coating produced in this way, and to the use thereof.
摘要:
An imitation gem consisting of a semi shell of a transparent plastic material with concave inner and convex outer surfaces has light reflecting and light refracting facets formed on both its inner concave and outer convex surfaces. The open end of the semi shell is closed by a cover which is also provided with facets so as to further improve light reflection and refraction.
摘要:
A process for the production of iridescence on synthetic polymeric surfaces by applying to the surface as a film of variable thickness adequate to produce iridescence within the visible spectrum a titanium compound having the general formula Ti(X)4 in which X represents a halogen atom or a (-OR) group and subsequent to application of the film ageing the treated surface at a temperature above 85* C. The titanium compound is preferably titanium tetrachloride although organic titanates are also useful and the synthetic polymeric surface is preferably a surface formed of polyethylene terephthalate.
