(57) Abstract: A coating material for protecting an image, particularly an image formed by a water-based ink, is provided. A composition which contains a colloidal silica-containing acrylic resin emulsion and a compound represented by the general formula (1) and which can form a coating having improved water resistance without cracking during dry film formation is obtained. General formula (1) A in the formula is Embedded image Embedded image And n represents an integer of 1 to 3. Also, R 1 And R 2 may be the same or different and each represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an acyl group having 1 to 4 carbon atoms, or a glycidyl group. (However, Except when R 1 and R 2 are simultaneously a hydrogen atom. ) |
