【０００２】
【従来の技術と発明が解決しようとする課題】
内装用壁装材の表面が汚れて、その補修をするとき、古い壁装材をはがし、そのまま新しい壁装材を塗った場合、下地材である土壁、木材、セメントモルタル等の表面あるいは内部に存在するリグニン、あるいはたばこのやに、その他一般的にあくと称される汚染物質により補修した表面が汚染される。これを防ぐために、下地材に汚染防止剤を塗布するか、あるいは内装用壁装材組成物中に、汚染防止剤を混入している。また、障子紙が汚れて、その補修をするとき、古い障子紙をはがし、そのまま新しい障子紙を張った場合、上記内装用壁装材の場合と同様、下地材である木材のあくにより、新しい障子紙が汚染される。これを防ぐために接着材中に汚染防止剤を混入している。さらに、塗料で塗装する場合、汚染防止剤を塗料中に混入するか、塗装面にあらかじめ塗布することにより、塗装面が汚染されないようにしている。汚染防止剤としては、いずれの場合もジシアンジアミド・ホルムアルデヒド系縮合物が効果的であり、よく使用されている。
【０００３】
