THERMOPLASTIC MATERIAL COMPRISING POLYCHROMIC SUBSTANCES. |
摘要 |
The present invention relates to thermoplastic material comprising polymer and at least one polychromic substance, wherein the polychromic substance is a functionalised diacetylene having the formula which has the general structure: X-C C-C C-Y-(CO)n -QZ wherein X is H or alkyl, Y is a divalent alkylene group, Q is O, S or NR, R is H or alkyl, and Z is alkyl, and n is 0 or 1. The present invention further relates to a method of processing thermoplastic material to form a plastic article, wherein the method comprises the step of processing the thermoplastic material at a temperature greater than the melt temperature of the thermoplastic, wherein the thermoplastic material comprises polymer and at least one polychromic substance as defined above; and further comprising the step of irradiating the plastic article to colour at least a region of the plastic article. |
