Abstract
A method for making a heat treatable coated article including a composite oxide coating with ultraviolet (UV) radiation blocking properties is provided. The composite oxide coating may be formed by applying, then optionally curing, a wet coating solution including a mixture of titanium, ceria, and silica to the substrate over an optional infrared (IR) blocking multi-layer coating (e.g., low-E coating). The ceria, titania, and silica may act as UV blocker(s). An organic polymer top coating may be provided over the composite oxide, where the organic polymer may be formed by exposing a photomonomer and/or photopolymer to radiation (e.g., UV radiation). The coated glass substrate may then be subjected to a high temperature heat treatment step. The coating may be heat and/or crack resistant. The coated article may be effective at blocking IR and/or UV radiation in applications such as window applications.
