the above defined solvent system also were added the resulting solution was clear the same procedure as in a was followed the dry film was smooth but cloudy one hundred percent coverage with electroless nickel was achieved an additional 10 milliliters of i were added to the composite material system of j the same procedures as in j were followed and yielded the same results except that the dry film was clear five milliliters of ii and 5 milliliters of iv were added to the composite material system of c an additional 20 milliliters of the above defined solvent system also were added the resulting solution was clear the same procedure as in a was followed the dry film was clear and smooth one hundred percent coverage with electroless nickel was achieved ten milliliters of i 10 milliliters of ii 2 milliliters of iii 2 milliliters of iv and 20 milliliters of the above described solvent system were mixed the resulting solution was clear the same procedure as in a was followed the dry film was clear and smooth one hundred percent coverage with electroless nickel was achieved the procedure of m was repeated except that the coating was peeled off prior to electroless plating the thickness of the coating was 0 3 mil the procedure was again repeated except that two and three coatings were applied to the glass slide these coatings had thicknesses of 0 6 mil and 0 9 mil respectively plating on the double and triple coated slides gave one hundred percent coverage with electroless nickel a thermally reticulated polyurethane foam was coated with about 0 3 mil thickness of a hydrophilic composite material the hydrophilic composite material contained 4 grams polyvinylpyrrolidone 8 grams of a.
