Abstract

Official abstract text for this publication.

This invention relates to a laser-marking additive wherein the laser-marking additive comprises a bismuth containing compound and a functionalized polymer having 0.01 to 50 wt % of functional groups, in which the weight percentage is based on the total amount of functionalized polymer and bismuth containing compound. The invention further relates to a method for preparation of such laser-marking additive, a laser-markable composition comprising such laser-marking additives and preparation thereof and molded parts comprising the laser-markable composition, as well as films made from the laser-markable composition.

First claim

Opening claim text (preview).

The invention claimed is: 1. A laser-marking additive comprising: a functionalized carrier polymer, and a bismuth-containing compound melt-blended with the functionalized carrier polymer, wherein the bismuth-containing compound is at least one selected from the group consisting of Bi 2 O 3 and Bi-citrate, and wherein the functionalized carrier polymer comprises an amount of functional groups based on total weight of the functionalized polymer and the bismuth-containing co…
