Claims
- 1. A storage stable prepreg comprising an epoxy resin or a polyurethane resin containing a neutral metal complex salt with additional coordinated ligands prepared by reacting a complex-forming metal salt of the metal M as defined below with a chelating ligand and a Lewis base in water and the optional presence of a solubilizer and an inorganic auxiliary base which forms a soluble salt with the acid radical of the metal salt in stoichiometric amounts while inputting energy in the form of a member selected from the group consisting of shear forces, ultra sound, microwaves and laser beams to form neutral complexes and recovering the product in fine crystalline form, the reaction being represented by the equation: ##STR3## wherein M is a metal ion selected from the group consisting of cobalt, nickel, iron, zinc, manganese, copper, mercury, zirconium, tin, cadmium, titanium, vanadium, indium, silver, chromium and antimony, SR is an acid radical of an organic or inorganic acid, B is a Lewis base and L is a chelating ligand, wherein

- 3. An epoxy resin or mixture of epoxy resins containing as the sole curing catalyst a neutral metal complex salt with additional coordinated ligands prepared by reacting a complex-forming metal salt of the metal M as defined below with a chelating ligand and a Lewis base in water and the optional presence of a solubilizer and an inorganic auxiliary base which forms a soluble salt with the acid radical of the metal salt in stoichiometric amounts while inputting high energy to form neutral complexes and recovering the product in fine crystalline form, the reaction being represented by the equation: ##STR5## wherein M is a metal ion selected from the group consisting of cobalt, nickel, iron, zinc, manganese, copper, mercury, zirconium, tin, cadmium, titanium, vanadium, indium, silver, chromium or antimony, SR is an acid radical of an organic or inorganic acid, B is a Lewis base and L is a chelating ligand, wherein
- m.multidot.a=b.multidot.n.gtoreq.m (c.multidot.x)
- x.multidot.c.ltoreq.a and n/m=p, m.multidot.o.ltoreq.p, and
- a=an integer of 1-8,
- b=an integer of 1-3,
- c=an integer of 0-4,
- m=an integer of 1-3,
- n=an integer of 1-8,
