Abstract
Method for the production of a laser-inscribable sheet of glass, wherein a laser-sensitive coating, comprising a) a base polymer and b) a radiation-sensitive additive which exhibits a color change on laser irradiation, is applied to at least part of a sheet of glass and hardened, and the sheet of glass is subsequently inscribed by means of a laser.
Claims8
A method for the production of a laser-inscribable sheet of glass, comprising the steps of:
- a) providing a laser-sensitive coating, comprising
- i) a base polymer and
- ii) a radiation-sensitive additive which exhibits a color change upon laser irradiation;
- b) applying said coating in liquid form to at least part of a sheet of glass;
- c) hardening said coating by radiation-chemical curing;
- and subsequently
- d) inscribing the coating by means of a laser.

Process for the production of an inscribable multilayer glass, comprising the steps of, in order:
- a) bonding two glass sheets to one another in such a way that a cavity remains between them,
- b) filling the cavity present between the glass sheets with a coating material to such an extent that only a small partial region remains,
- c) introducing into the partial region a laser-sensitive coating material comprising
- i) a base polymer and
- ii) a radiation-sensitive additive which exhibits a color change upon laser irradiation,
- d) carrying out a radiation-chemical hardening of the coating, and
- e) inscribing the multilayer glass by means of a laser.
