The design and development of dyes and chromophores have recently attracted much attention in various research fields such as materials, radiation curing, (laser) imaging, optics, medicine, microelectronics, nanotechnology, etc.. In this book, the recent research for the use of dyes and chromophores in polymer science is presented. The interaction of the visible light with the dyes or the selected chromophores is particularly important in different fields (e.g. for photovoltaic, display applications (LED …), laser imaging or laser direct writing, green chemistry with sunlight induced photopolymerization etc …). This book gives an overview of the dyes and chromophores for all the important fields.
