Zusammenfassung: | To provide ink compositions for surface printing that can form a print layer excellent in gloss.SOLUTION: An ink composition for surface printing contains a polyamide resin (A), nitrocellulose (B), a cellosolve solvent (D), and an organic solvent (E) other than the cellosolve solvent (D). The content of the polyamide resin (A) is 3-40 mass% based on the total mass of the ink composition for surface printing. The content of the nitrocellulose (B) is 0.5-28 mass% based on the total mass of the ink composition for surface printing. The content of the cellosolve solvent (D) is 0.1-20 mass% based on the total mass of the ink composition for surface printing. The type and viscosity symbol of the nitrocellulose (B) specified by viscosity measurement according to JIS K 6703:1995 are H1/8, H1/4, H1/2, H1 or H2.SELECTED DRAWING: None
【課題】光沢に優れる印刷層を形成できる表刷り用インキ組成物の提供。【解決手段】ポリアミド樹脂(A)と、ニトロセルロース(B)と、セロソルブ系溶剤(D)と、前記セロソルブ系溶剤(D)以外の有機溶剤(E)とを含有する表刷り用インキ組成物であって、前記ポリアミド樹脂(A)の含有量が、前記表刷り用インキ組成物の総質量に対して3~40質量%であり、前記ニトロセルロース(B)の含有量が、前記表刷り用インキ組成物の総質量に対して0.5~28質量%であり、前記セロソルブ系溶剤(D)の含有量が、前記表刷り用インキ組成物の総質量に対して0.1~20質量%であり、前記ニトロセルロース(B)のJIS K 6703:1995に準拠した粘度測定によって規定される種類及び粘度記号が、H1/8、H1/4、H1/2、H1又はH2である、表刷り用インキ組成物。【選択図】なし |
