Elga s.r.l. was founded in 1973 and was set up to sell chemical products for the printed-circuit industry, manufactured by Lea Ronal Inc.
In 1979 the company became Elga Ronal upon the finalization of a joint venture with Lea Ronal.
Following a joint venture between T.O.K. Japan and Elga Ronal in 1995 the company started manufacturing dry film wholly in Italy and to distribute the product throughout Europe and Western countries.
The company became 100% Italian in 1999 under the name of Elga Europe s.r.l.
The joint venture with T.O.K. Japan ended in 2010 and Elga Europe acquired all the shares and owned the manufacturing site.
In 2013 Elga Europe and Eternal formed joint venture whereby Eternal is acquiring a minority stake in the corporate capital of Elga.
Eternal dry film products from 1st of January 2014 will be stocked, distributed and technically supported by Elga Europe solely in the European market.
