Document Type and Number:
Japanese Patent JP7068970
Kind Code:
B2
Abstract:
To provide a laminate capable of maintaining a removal effect of formaldehyde for a long time and to provide a method for producing the same.SOLUTION: There is provided a laminate 1 having a substrate 11, a drug-containing layer 12 and a coating layer 14, wherein the drug-containing layer 12 is disposed between the substrate 11 and the coating layer 14, the coating layer 14 is the uppermost surface layer of the laminate 1, the drug-containing layer 12 contains a microencapsulated formaldehyde reactant and a non-microencapsulated formaldehyde reactant, the coating layer 14 is obtained by blending one or both of a microencapsulated formaldehyde reactant and a non-microencapsulated formaldehyde reactant and is formed using a composition for forming a coating layer having a viscosity of 90 to 14200 mPa s.SELECTED DRAWING: Figure 1
