A retroreflective micro sealed prismatic sheeting, comprising: a retroreflective layer (110, 310) comprising multiple cube corner elements (112, 312) that collectively form a structured surface (114, 314) that is opposite a major surface (116, 316); a pressure sensitive adhesive layer (130, 330) comprising crosslinked tackified acrylic pressure-sensitive adhesive and having a first region and a plurality of second regions wherein the second regions are in contact with the structured surface; and a barrier layer (134, 580) disposed between the structured surface (114, 314) and the first region of the adhesive layer (130, 330) having sufficient structural integrity to substantially prevent flow of the pressure sensitive adhesive into the first region; wherein the first region with the barrier layer (134, 580) and the second regions have sufficiently different properties to form a low refractive index layer (138, 338) having an index of refraction of less than 1.3 between the pressure sensitive adhesive layer (130, 330) and the structured surface (114, 314) of the retroreflective layer (110, 310) such that the pressure sensitive adhesive that contacts at least a portion of the structured surface (114, 314) forms an optically inactive area that does not substantially retroreflect incident light; and the low refractive index layer (138, 338) between the barrier layer (134, 580) and a portion of the structured surface (114, 314) forms an optically active area that retroreflects incident light; wherein the retroreflective sheeting has a uniform white appearance; wherein the CAP Y is greater than 50; and wherein the retroreflective sheeting comprises a roadway sign, a traffic control sign, a street sign, a highway sign, a licence plate, a delineator, a barricade, a personal safety product, a safety vest, a display signage, or vehicle graphics. a retroreflective layer (110, 310) comprising multiple cube corner elements (112, 312) that collectively form a structured surface (114, 314) that is opposite a major surface (116, 316); a pressure sensitive adhesive layer (130, 330) comprising crosslinked tackified acrylic pressure-sensitive adhesive and having a first region and a plurality of second regions wherein the second regions are in contact with the structured surface; and a barrier layer (134, 580) disposed between the structured surface (114, 314) and the first region of the adhesive layer (130, 330) having sufficient structural integrity to substantially prevent flow of the pressure sensitive adhesive into the first region; wherein the first region with the barrier layer (134, 580) and the second regions have sufficiently different properties to form a low refractive index layer (138, 338) having an index of refraction of less than 1.3 between the pressure sensitive adhesive layer (130, 330) and the structured surface (114, 314) of the retroreflective layer (110, 310) such that the pressure sensitive adhesive that contacts at least a portion of the structured surface (114, 314) forms an optically inactive area that does not substantially retroreflect incident light; and the low refractive index layer (138, 338) between the barrier layer (134, 580) and a portion of the structured surface (114, 314) forms an optically active area that retroreflects incident light; wherein the retroreflective sheeting has a uniform white appearance; wherein the CAP Y is greater than 50; and wherein the retroreflective sheeting comprises a roadway sign, a traffic control sign, a street sign, a highway sign, a licence plate, a delineator, a barricade, a personal safety product, a safety vest, a display signage, or vehicle graphics.
