Abstract
The invention pertains to a composition comprising silver metal particles and an additive, characterized in that the additive is a silane derivative comprising at least one methyl group and at least one alkoxy group. Preferably, the silane derivate is methyl trimethoxysilane, methyl triethoxysilane, or a mixture thereof. The compositions can be used to make thermal resistant conductive silver-containing layers, for instance for use in AMLCD.
Claims6
An active matrix liquid crystalline display (AMLCD) comprising a silver containing layer adjacent to a silsesquioxane layer.
A method for making an active matrix liquid crystal display, comprising:
- a) providing a composition, wherein the composition comprises silver metal and a silane derivative, wherein the silane derivative is a methylalkoxysilane;
- b) applying the composition to a substrate;
- and
- c) heating the composition applied in said step b), wherein said heating the composition in said step c) results in the completion of the following steps i)–iii):
- i) forming a first layer on said substrate, said first layer comprising silver metal;
- ii) decomposing the silane derivative to form silsesquioxane;
- and
- iii) forming a second layer adjacent to the first layer, wherein the second layer comprises silsesquioxane, silicon dioxide, or a mixture thereof.
