Easily applicable adhesive sheet which can be easily applied neatly in good adhesion with easy air removal at the time of application to an adherent and a producing method thereof are provided. An easily applicable adhesive sheet having, on the surface of a substrate, an adhesive layer in which a plurality of spherical protrusions are disposed and an air flow channel is formed between adjacent protrusions, and the spherical protrusion has a diameter of from 50 to 300 µm, a height of from 10 to 50 µm and a distance between the adjacent protrusions of from 0 to 100 µm, and a method for producing an easily applicable adhesive sheet as described above, by applying an adhesive layer formed on a shape-transfer face of a release liner to a substrate.
L'invention concerne une nouvelle feuille adhésive facile à coller. Quand on la colle sur un objet, l'air s'échappe facilement de dessous de la feuille, ce qui permet de l'attacher facilement et proprement avec une excellente adhésion. L'invention concerne également le procédé de production de cette feuille adhésive. La feuille adhésive facile à coller est pourvue d'une feuille support dotée d'une couche de colle présentant une pluralité de protubérances sphériques formant des passages de communication d'air entre les protubérances adjacentes. Ces protubérances ont un diamètre de 50 à 300 mu m et une hauteur de 10 à 50 mu m. La feuille adhésive est produite par liaison de la couche adhésive formée sur la face de transfert de forme d'une feuille pelable et de la surface de la feuille support.
