<P>PROBLEM TO BE SOLVED: To solve such a problem that improvement in practical use of a metal-containing collagen has been required in practical application of collagen containing a metal such as aluminum because there is a problem of a state of application due to technical restriction in working of collagen such as a state with which the function is fulfilled is restricted to a powder state, a fiber state, or a work state in which collagen is directly applied and made insoluble, moreover restriction of applicable articles, that is, states of products, and also there is a problem of cost increase caused by such working. <P>SOLUTION: An aqueous solution including: a polypeptide whose concentration is in the range of 0.00001-6 wt.%; and a metal whose concentration is in the range of 0.025-0.5 wt.% or 0.000002-0.02 wt.%, turns out to be an aqueous solution in which a metal-containing collagen is kept in a condition of stable dissolution in water without giving rise to insolubilization, and imparts an anti-bacterium and anti-allergenition function to articles in various shapes with spray treatment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
