LIGHT-TRANSMITTING SUBSTRATE PROVIDED WITH A LIGHT-ABSORBING COATING

摘要

Disclosed is a light-transmitting substrate that is at least partly provided with a light-absorbing coating. Said coating comprises silver or gold particles that are incorporated in a sol-gel matrix. In order to improve the transmittance in red and to reduce the amount of silver and gold particles, a blue-absorbing compound is added to the coating. Furthermore, an electric lamp is disclosed, said lamp comprising a light-transmitting lamp vessel that accommodates a light source. Said lamp vessel comprises the above light-transmitting substrate. Moreover, a light-absorbing coating is disclosed.
