I had experience working with positive dry type photoresist.Make it a rule not to remove the pvc coating of the copper board in exposed light.Use a partially lit environment and you will be amazed your problem will be solved. Ensure that the coating is not injured also.With the correct developer concentration and etching time ,your board will come out just fine.The process is your problem not the material ,i think.Good luck!
