Abstract
Official abstract text for this publication.
The present invention provides a hot melt pressure-sensitive adhesive being highly environmentally-friendly, as well having sufficient adhesion, thermal stability and coating performance, and also having an excellent hand-peeling property and alkali-peeling property. The present invention relates to a hot melt pressure-sensitive adhesive for labeling comprising: (A) a polar functional group-modified conjugated diene-based polymer, (B) an aliphatic polyester-based resin, and (C) a tackifier resin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hot melt pressure-sensitive adhesive for labeling comprising: (A) a polar functional group-modified conjugated diene-based polymer having a weight average molecular weight range of 7.5×10 4 to 1.0×10 5 , (B) an aliphatic polyester-based resin, and (C) a tackifier resin. 2. The hot melt pressure-sensitive adhesive for labeling according to claim 1 , wherein the polar functional group-modified conjugated diene-based polymer (A) is a hydrogenated conjugated diene-based polymer having at least one functional group selected from an acid anhydride group, a maleic acid group, a carboxyl group, an amino group, an imino group, an alkoxysilyl group, a silanol group, a silyl ether group, a hydroxyl group and an epoxy group. 3. The hot melt pressure-sensitive adhesive for labeling according to claim 1 , wherein the polar functional group-modified conjugated diene-based polymer (A) comprises at least one selected from an amino group-modified styrene-ethylene/butylene-styrene block copolymer and a maleic acid group-modified styrene-ethylene/butylene-styrene block copolymer. 4. The hot melt pressure-sensitive adhesive for labeling according claim 1 , wherein the aliphatic polyester-based resin (B) is at least one selected from a polylactic acid and a poly(butylene succinate). 5. A label on which the hot melt pressure-sensitive adhesive for labeling according to claim 1 is applied. 6. A container to which the label according to claim 5 is adhered. 7. A hot melt pressure-sensitive adhesive for labeling comprising: (A) a polar functional group-modified styrene-ethylene/butylene-styrene block copolymer, (B) an aliphatic polyester-based resin, and (C) 20 to 40 parts, based on the total weight of the adhesive, of a tackifier resin. 8. The hot melt pressure-sensitive adhesive of claim 7 , wherein the polar functional group-modified styrene-ethylene/butylene-styrene block copolymer is an amino group-modified styrene-ethylene/butylene-styrene block copolymer and/or maleic acid group-modified styrene-ethylene/butylene-styrene block copolymer.
