Abstract: front page image
(EN)A pressure-sensitive adhesive composition for an optical member which comprises a (meth)acrylic polymer, a solvent (A) based on a hydrocarbon having 6 to 9 carbon atoms and a high boiling point and high solubility solvent (B) having a boiling point higher than that of the above hydrocarbon solvent and exhibiting the solubility for the (meth)acrylic polymer higher than that of the above hydrocarbon solvent, wherein the content of the solvent (A) based on the hydrocarbon is 20 to 60 wt % relative to the total amount of the solvents, and the ratio of the content (wt %) of the solvent (A) based on the hydrocarbon to that (wt %) of the high boiling point and high solubility solvent (B) (high boiling point and high solubility solvent (B)/hydrocarbon- based solvent (A)) is 0.05 to 4. The above pressure-sensitive adhesive composition for an optical member exhibits good applicability due to a reduced viscosity thereof, allows the reduction of the amount of an organic solvent to be used, and further can form a pressure-sensitive adhesive layer being excellent in durability and having a highly uniform surface.
(FR)L’invention concerne une composition d'adhésif sensible à la pression destinée à un élément optique qui comprend un polymère (méth)acrylique, un solvant (A) à base d’un hydrocarbure ayant de 6 à 9 atomes de carbone et un point d’ébullition élevé, et un solvant (B) de solubilité élevée dont le point d’ébullition et l’aptitude à solubiliser le polymère (méth)acrylique sont supérieurs à ceux du solvant (A). La teneur en solvant (A) est de 20 à 60 % en poids par rapport à la quantité totale de solvants, et le rapport entre la teneur (% en poids) de solvant (A) et celle (% en poids) du solvant (B) (solvant (B)/solvant (A)) va de 0,05 à 4. Ladite composition d’adhésif sensible à la pression pour élément optique fait preuve d’une bonne applicabilité grâce à sa viscosité réduite, permet la réduction de la quantité de solvant organique à utiliser et peut en outre former une couche d’adhésif sensible à la pression offrant une durabilité excellente et une surface d’une grande uniformité.
(JA) 粘度が小さいため塗工性がよく、有機溶媒使用量の削減が可能であり、さらに耐久性に優れかつ表面均一性の高い粘着剤層を形成することのできる光学部材用粘着剤組成物を提供することを目的とする。本発明の光学部材用粘着剤組成物は、(メタ)アクリル系ポリマー、炭素数6~9の炭化水素系溶媒(A)、及び前記炭化水素系溶媒よりも沸点が高くかつ前記炭化水素系溶媒よりも(メタ)アクリル系ポリマーの溶解性が高い高沸点高溶解性溶媒(B)を含有しており、前記炭化水素系溶媒(A)の含有量が全有機溶媒の20~60重量%であり、かつ前記高沸点高溶解性溶媒(B)の含有量(重量%)に対する前記炭化水素系溶媒(A)の含有量(重量%)の比(高沸点高溶解性溶媒(B)/炭化水素系溶媒(A))が0.05~4である。
