Method and liquid composition for marking substrates made of plastics
material
摘要:
A method of forming a mark on a substrate made of plastics material comprises the step of applying a basic solution to a surface portion having a prefixed pattern of the substrate. In a preferred embodiment, the basic solution is used in combination with at least one alkali-stable water-soluble polymer, to produce a viscous liquid composition, which is advantageously applicable to the substrate by means of pad-printing and silk-screen printing process.
