Abstract: The invention includes a process for forming a laser pixel array useful with a pump-beam, comprising: a) forming a layer containing a formamide of an amino dye compound on a support wherein the layer absorbs light outside the laser wavelength and predominantly outside the pump-beam wavelength range; and b) subjecting the layer to UV radiation in the areas of the layer where it is desired to be free of pixels for a time sufficient to shift the absorption envelope of the areas into the pump-beam wavelength range. The invention also provides for unimolecularly forming an image or an information record and a composition of matter. The invention provides methods for forming filters, images or information records having a smooth surface and in particular for forming a pixel region pattern for use with an Organic VCSEL that would ease manufacturing.
