Abstract: PROBLEM TO BE SOLVED: To produce a uniform coating simply and promptly by setting a process in which a kind of crosslinking reaction is started in a kind of reactive coat composition and a process in which the composition is applied on an area of the surface of a substrate before the generation of the crosslinking reaction. SOLUTION: At least one kind of reactive coat composition is supplied from a storage container to a coating apparatus having a nozzle 6. The light of an exposure apparatus 1 (preferably a UV exposure apparatus, especially a UV laser) is guided from a closure 2 to the coating apparatus (especially just before the nozzle 6) through optical wave guides 3, 4. The composition receives UV exposure directly in the discharge opening clearance of the nozzle 6 before leaving the coating apparatus by each optical wave guide 3, 4. As a result, the crosslinking reaction of the composition is started. The crosslinking reaction is selected or controlled to be started just before the discharge opening clearance when a trigger is not yet advanced.

SOLUTION: This method for producing a (meth)acrylic ester comprises esterifying acrylic acid and/or methacrylic acid with at least one compound having at least one alcoholic hydroxyl group while adding to the reaction system a hydrocarbon with a boiling point of 60-140 deg.C as a water azeotropic agent at 90-150 deg.C in the presence of an acidic esterification catalyst and a polymerization inhibitor, and after esterification, distilling the water azeotropic agent and excess (meth)acrylic acid off at 90-150 deg.C under a normal or reduced pressure, and if necessary, neutralizing the product obtained after distillation with at least one basic inorganic compound, wherein a copper (II) salt or a mixture composed of the copper (II) salt and a copper (I) salt to be deposited after esterification as a copper sulfide and separated is used as the polymerization inhibitor.
