Compositions, particularly pressure sensitive adhesive compositions, such as hot melt pressure sensitive adhesive compositions, and laminates using the compositions are disclosed. Specifically, hot melt pressure sensitive adhesive compositions, comprising: a polyol ester; a styrene- isoprene-styrene block copolymer; a cling agent; a photoinitiator; and a naphthenic oil; or a composition comprising: a styrene-isoprene-styrene block copolymer; a polybutene polymer; a photoinitiator; and a tackifier; and related laminate and label constructions thereof are discussed herein. L'invention concerne des compositions, en particulier des compositions adhésives sensibles à la pression, telles que des compositions adhésives sensibles à la pression thermofusibles, et des stratifiés utilisant les compositions. Plus particulièrement, l'invention concerne des compositions adhésives sensibles à la pression thermofusibles, comprenant : un ester de polyol ; un copolymère séquencé de styrène-isoprène-styrène ; un agent d'auto-adhérence ; un photoinitiateur ; et une huile naphténique ; ou une composition comprenant : un copolymère séquencé de styrène-isoprène-styrène ; un polymère de polybutène ; un photoinitiateur ; et un agent tackifiant ; et des constructions de stratifiés et d'étiquettes associées.
