摘要:
Provided is a metal-coating material excellent in sulfur barrier property and transparency, a method for protecting a metal using the metal-coating material, and a light emitting device permitting high luminance and long life. The metal-coating material contains a polymer (A) obtained by subjecting at least one silane compound (a1) selected from the group consisting of at least one organosilane represented by the formula (1) : R 1 n Si(OR 2 ) 4-n , wherein R 1 means a monovalent organic group having 1 to 8 carbon atoms, with the proviso that when two organic groups are present, the groups may be the same or different from each other, R 2 denotes, independently of each other, an alkyl group having 1 to 5 carbon atoms or an acyl group having 1 to 6 carbon atoms, and n is an integer of 0 to 2, a hydrolyzate of the organosilane and a condensate of the organosilane, and a polymer (a2) having a silyl group containing a silicon atom bonded to a hydrolyzable group and/or a hydroxyl group to a hydrolyzing and condensation reaction.
