Variegated color and optimally textured effects are produced on substantially non-wicking surfaces by applying gel particles of at least two different colors formed from at least two alginate compositions, each containing a different color from the other and each having been mixed with a second composition containing a gelling agent to produce the particles.

Coloring process

Synthetic fluorhectorite films impregnated with polyimide resin are stacked, press-laminated and post-cured to produce a printed wiring board substrate with thermal expansion matching ceramic components. The substrate can be cleanly drilled for through-holes and plated without the need to remove residue as with glass/epoxy boards.
