A foamlike pressure-sensitive adhesive tape can be produced by photopolymerization and yet have a dark appearance when dispersed throughout its pressure-sensitive adhesive layer are glass microbubbles to which are adhered dyed, finely divided silica particles. The dyed glass microparticles also are useful as fillers in other articles to which they can impart surprisingly intense coloring. In spite of the good hiding power afforded by the dyed glass microparticles, they do not unduly inhibit photopolymeriz- ing radiation of normally transparent materials into which they can be dispersed.
