Claim 2

A PROCESS WHICH COMPRISES COATING AN INERT BASE MEMBER WITH A HOT MELT CONSISTING OF A CONDENSATION PRODUCT OF STOICHIOMETRIC PROPORTIONS OF A SATURATED, ALIPHATIC, STRAIGHT-CHAIN DICARBOXYLIC ACID HAVING AT LEAST FOUR CARBON ATOMS AND A MEMBER SELECTED FROM THE GROUP CONSISTING OF COMPOUDS REPRESENTED BY THE FOLLOWING FORMULA: HO(CNH2N) CH2OH IN WHICH N IS AN INTEGER OF FROM 1-3, INCLUSIVE, MONOETHANOL AMINE, 1-AMINO-2HYDROXY PROPANE, 1-AMIMO-3-HYDROXY BUTANE,1-HYDROXY2-AMINO PROPANE, 1-AMINO-2-HYDROXY BUTANE, 1-AMINO-3HYDROXY BUTANE, 1-AMINO-4-HYDROXY BUTANE, 1-HYDROXY-2AMINO BUTANE, 1-HYDROXY-3-AMINO BUTANE AND 1-HYDROXY-12-METHYL-3-AMINO PROPANE, ALLOWING THE RESULTING COATING TO COOL TO A NON-TACKY FORM, TRANSFORMING SAID COATING BY APPLICATION OF HEAT OF FROM 200* F. TO 300* F. TO A TACKY STATE, PLACING SAID COATED BASE MEMBER IN CONTACT WITH AN INERT ELEMENT, TO WHICH IT IS DESIRED TO ADHERE THE BASE MATERIAL, DURING A PERIOD OF TIME SUBSEQUENT TO HEAT-ACTIVATION OF SAID COATING, WITHIN WHICH THE COATING RETAINS ITS TACKINESS, AND ALLOWING SAID CONDENSATION PRODUCT TO SET, THEREBY FORMING A STRONG ADHESIVE BOND BETWEEN SAID BASE MEMBER AND SAID ELEMENT, AND WHEREIN SAID RESIN HAS A NUMBER-AVERAGE MOLECULAR WEIGHT OF BETWEEN 800 AND 2500, INCLUSIVE.
