なわち２本発明の要旨は次に述べる通りである。Obtained the knowledge that clear marks can be obtained when a composite material consisting of a glass base material and a synthetic resin is prepared by attaching a laser light-absorbing substance to the glass base material and then wiping it, followed by laser marking.1 We have arrived at the present invention. That is, the gist of the present invention is as follows.
レーザー光吸収性物質を付着させたガラス基材と合成樹
脂からなり、レーザー光吸収性物質のガラス基材１００

A composite material having good laser marking properties, characterized in that the amount of adhesion to parts by weight is 5 x 10-s to 1 x 10-' parts by weight.
本発明において、ガラス基材におけるガラスは。In the present invention, the glass in the glass substrate is.
Ｅガラス、Ｃガラス、Ｓガラス等いずれでもよく。E glass, C glass, S glass, etc. may be used.
これらのガラスは、一般に波長３μｍ以下の光の吸収が
少ない。そして、これらのガラスは繊維として、あるい
はさらに不織布や織物等に加工して複合材料におけるガ
ラス基材として用いられる。These glasses generally have low absorption of light with a wavelength of 3 μm or less. Then, these glasses are used as fibers or further processed into nonwoven fabrics, textiles, etc., and used as glass substrates in composite materials.
合成樹脂としては何ら限定されず、エポキシ樹脂、ポリ

ング性が悪く不鮮明なマークしか得られない。As the laser light absorbing substance, black pigments or black dyes are preferably used, and carbon black is particularly preferred. The amount of laser light absorbing substance attached to the glass substrate is 5×1 per 100 parts by weight of the glass substrate.
0-5 to 1 x 10-' parts by weight. If it exceeds 1 x 10 -' parts by weight, even if other pigments are blended, it will only be achromatic, and if it is less than 5 x 10 -' parts by weight, the laser marking properties will be poor and only unclear marks will be obtained.
