Deep eutectic solvents: green solvents for the removal of degraded gelatin on cellulose nitrate cinematographic films
Abstract Cellulose nitrate (CN) has been used in the past as support for photographic negatives and cinematographic films. This material is particularly unstable and can undergoes severe degradation due to thermal, photocatalytic and hydrolytic loss of nitro groups from the lateral chain. Thus, to p...
