Abstract

An object of the present invention is to provide an aqueous composition for forming a hard coat layer having high alkali resistance and a hard coat layer. The present invention relates to an aqueous composition in which epoxy-containing alkoxysilanes, epoxy-free alkoxysilanes and metal complexes are mixed, compared to epoxy-containing alkoxysilanes For all alkoxysilanes composed of alkoxysilanes without epoxy groups, the proportion of alkoxysilanes containing epoxy groups is 20 to 85% by mass, relative to the alkoxysilanes containing epoxy groups , the proportion of the metal complex is 17-70 mol%.

Description

technical field [0001] The present invention relates to aqueous compositions and hardcoats. Specifically, the present invention relates to an aqueous composition comprising an epoxy group-containing alkoxysilane, an epoxy group-free alkoxysilane, and a metal complex, and a hard coat layer formed using the aqueous composition. Background technique [0002] In recent years, display devices such as liquid crystal displays, plasma displays, and touch panel displays have spread rapidly. The surfaces of these display devices are susceptible to injury due to contact with various objects. In addition, resistance to heat and humidity may also be required. Therefore, the surface of a display device is required to have high scratch resistance and high heat and humidity resistance. [0003] In order to provide the surface of the display device with high scratch resistance and high heat and humidity resistance, a hard coat layer is often provided on the surface layer of the display de...
