Moulded mass for producing objects that are poorly inflammable, pigment therefor, and use of the same |
摘要 |
A molding material for the production of highly flame resistant articles with a matrix formed from a thermoplastic and with a particulate flame retardant pigment dispersed therein, wherein under the influence of laser light the material changes color due to a change in color of the pigment or of the plastic matrix, and in that the pigment is a reaction product of at least one halogen-free flame retardant organic nitrogen base with a composition comprising at least one salt which can be reacted with the organic nitrogen base. The invention also includes a method for the preparation of a molding material as described above by the dispersion of a particulate flame retardant pigment to a plastic material, wherein under the influence of laser light the material changes color due to a change in color of the pigment or of the plastic matrix, and in that the pigment is a reaction product of at least one halogen-free flame retardant organic nitrogen base with a composition comprising at least one salt which can be reacted with the organic nitrogen base. The invention also includes a highly flame resistant and laser-writable plastic article comprising a formed material as described above.
