In a method for coating a calcium phosphate compound on a biotissue substrate or, particularly, in case the biotissue substrate is biotissue, there is provided a method for coating of biotissue substrate where the method causes no damage thereto, is very mild even to biotissues which are other than the biotissue to be coated and is able to form a uniform coat. A method for coating a calcium phosphate compound on a biotissue substrate by an alternate soaking method which is characterized in that, as the soaking solutions, there are used a solution containing a water-soluble calcium salt and borate and/or L-histidine and a phosphate solution.

Method for coating of biotissue substrates

As an ultraviolet absorbent material, ceric oxide sol which can be widely used in many fields using various solvent materials is obtained. An anionic aqueous sol is obtained by adding phosphoric acid and/or phosphate to cationic ceric oxide sol. It is a sol that can be applied to an emulsion paint. By further adding a cationic surface active agent to this sol, an organo-ceric oxide sol that can be applied to various organic solvents is formed. This sol may widely be used in utilities using various organic solvent materials, such as paint materials.
