Zusammenfassung:	POSITIVE, LAMINABLE PROOFING CONSTRUCTION Positive-acting, laminable imaging constructions often suffer from high levels of optical density in background areas. The optical density is provided by migratory colorant or photosensitive diazo oxide. The use of a base soluble organic binder with a substantially polar solvent which contains the colorant and diazo oxide in combination with a thermally softenable polymeric adhesive layer having a substantially non-polar solvent system prevents migration of colorant and diazo oxide between layers and reduces the background optical density.
