Solid marking composition as writing means, a writing instrument, an optically variable marking layer and use of a plurality of optically variable pigments

摘要：

A solid marking composition comprises a solid matrix containing at least one type of optically variable interference pigment flakes. The solid marking composition provides a document or article with a copy and counterfeit protection feature, and is preferably used in a writing instrument for applying hand-written anti-counterfeit markings and signatures.

摘要（中）：

固体标记组合物包含含有至少一种类型的光学可变干涉颜料薄片的固体基质。固体标记组合物提供具有复制和假冒保护特征的文件或制品，并且优选用于用于执行手写防伪标记和签名的书写工具。
