enetrant inspection process and compositions

Claim 1

AN INSPECTION PENETRANT LIQUID FOR DETECTING SURFACE-CONNECTED DEFECTS, SAID PENETRANT LIQUID CONSISTING ESSENTIALLY OF A SOLVENT AND AT LEAST ONE DYE DISSOLVED IN SAID SOLVENT, SAID SOL ENT CONSISTING OF AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF A. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS NAPHTLALENE AND EACH OF X AND Y IS AN ALKYL RADICAL CONTAINING FROM ONE TO THREE CARBON ATOMS, B. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS PHTHALATE (OR ISOPHTHALATE) AND EACH OF X AND Y IS AN ALKYL RADICAL CONTAINING FROM SIX TO 10 CARBON ATOMS, C. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS SATURATED DICARBOXYLATE, WHERE THE NUMBER N OF THE CH2 RADICALS IN THE DICARBOXYLATE NUCLEUS IS IN THE APPROXIMATE RANGE OF 0-34, AND EACH OF X AND Y IS AN ALKYL RADICAL CONTAINING FROM SIX TO 10 CARBON ATOMS, D. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS PHENOL AND EACH OF X AND Y IS AN ALKYL RADICAL CONTAINING FROM EIGHT TO 12 CARBON ATOMS, E. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS PHENOL, X IS AN ALKYL RADICAL CONTAINING FROM EIGHT TO 12 CARBON ATOMS, AND Y IS AN ETHOXY GROUP CONTAINING FROM ZERO TO 5 MOLS OF ETHYLENE OXIDE PER MOL OF R, AND F. A NORMALLY LIQUID SOLVENT OF THE GENERIC FORMULA X-(R)-Y IN WHICH R IS 4.5-EPOXY-TETRAHYDROPHTHALATE AND EACH OF X AND Y IS AN RADICAL CONTAINING FROM SIX TO EIGHT CARBON ATOMS, SAID SOLVENT BEING PRESENT IN SAID INSPECTION PENETRANT LIQUIDIN A WEIGHT CONCENTRATION WITHIN THE APPROXIMATE RANGE OF 2 TO 98 PERCENT, SUFFICIENT TO PROVIDE AN EMULSIFICATION COEFFICIENT SMALLER THEN 50.
