Abstract
Official abstract text for this publication.
There is provided a protective film agent with which a workpiece is coated when the workpiece is processed. The protective film agent includes a water-soluble resin, a light absorbing agent having a flavone structure, a flavonol structure, or an isoflavone structure, and a solvent that dissolves the resin and the light absorbing agent.
First claim
Opening claim text (preview).
What is claimed is: 1. A protective film agent with which a workpiece is coated when the workpiece is processed, the protective film agent comprising: a water-soluble resin; a light absorbing agent; and a solvent that dissolves the resin and the light absorbing agent, and wherein the light absorbing agent contains a transglycosylated compound, and the solvent contains water, and further wherein the transglycosylated compound is transglycosylated rutin. 2. The protective film agent according to claim 1 , wherein the resin is polyvinyl alcohol, polyvinylpyrrolidone, hydroxypropyl cellulose, or polyoxazoline. 3. The protective film agent according to claim 1 , wherein the protective film agent contains such an amount of the light absorbing agent that absorbance at a wavelength of 355 nm becomes equal to or higher than 5.0 in terms of a state in which the protective film agent is diluted 200-fold with water and when measurement is executed with a thickness of 1 cm. 4. The protective film agent according to claim 1 , wherein the weight-average molecular weight of the water-soluble resin is equal to or lower than 250000. 5. A protective film agent with which a workpiece is coated when the workpiece is processed, the protective film agent comprising: a water-soluble resin; a light absorbing agent; and a solvent that dissolves the resin and the light absorbing agent, and wherein the light absorbing agent contains a transglycosylated compound, and the solvent contains water, and further wherein the transglycosylated compound is transglycosylated rutin or transglycosylated hesperidin. 6. The protective film agent according to claim 5 , wherein the resin is polyvinyl alcohol, polyvinylpyrrolidone, hydroxypropyl cellulose, or polyoxazoline. 7. The protective film agent according to claim 5 , wherein the protective film agent contains such an amount of the light absorbing agent that absorbance at a wavelength of 355 nm becomes equal to or higher than 5.0 in terms of a state in which the protective film agent is diluted 200-fold with water and when measurement is executed with a thickness of 1 cm. 8. The protective film agent according to claim 5 , wherein the weight-average molecular weight of the water-soluble resin is equal to or lower than 250000.
