A water dilutable resin composition comprising a resin that is a reaction product of an aldehyde, urea, and glycerol, wherein the composition obtainable by a process comprising the steps: combining an aldehyde solution with urea in a basic solution to form a mixture, wherein the composition has an initial molar ratio before condensation, of aldehyde to urea of 1.5 - 4.5; heating the mixture to a reaction temperature for methylolation; cooling the mixture to a condensation temperature; acidifying the mixture to a pH between 2.5 and 7.5; condensating the mixture to a desired condensation degree; adding glycerol at the end stage, before-, during- or after condensation of the resin or to the mixture before methylolation and optionally additionally after condensation; adding after condensation a further amount of urea such that the resin composition has an end molar ratio of aldehyde to urea between 1.0 and 3.0 and wherein the resin has an end molar ratio of urea to glycerol between 4 and 40, wherein the desired condensation degree is chosen to achieve a desired water dilutability of the resin composition of greater than 50 parts water to one part resin composition, wherein the pH measurement is made according to DIN 19263, wherein the water dilutability is determined by weighting 3g of the resin composition into an Erlenmeyer flask; recording the weight at a precision of 0.01 grams; adjusting the temperature of the sample to 20°C; titrating the sample with distilled water at 20 +/- 1°C while mixing thoroughly until small particles of precipitate appear on further addition of water, and result is calculated as follows: x = V ml / w g V is Volume of distilled water added (ml); w is Sample weight (g); Water tolerance ratio is 1 : x . combining an aldehyde solution with urea in a basic solution to form a mixture, wherein the composition has an initial molar ratio before condensation, of aldehyde to urea of 1.5 - 4.5; heating the mixture to a reaction temperature for methylolation; cooling the mixture to a condensation temperature; acidifying the mixture to a pH between 2.5 and 7.5; condensating the mixture to a desired condensation degree; adding glycerol at the end stage, before-, during- or after condensation of the resin or to the mixture before methylolation and optionally additionally after condensation; adding after condensation a further amount of urea such that the resin composition has an end molar ratio of aldehyde to urea between 1.0 and 3.0 and wherein the resin has an end molar ratio of urea to glycerol between 4 and 40, wherein the desired condensation degree is chosen to achieve a desired water dilutability of the resin composition of greater than 50 parts water to one part resin composition, wherein the pH measurement is made according to DIN 19263, wherein the water dilutability is determined by weighting 3g of the resin composition into an Erlenmeyer flask; recording the weight at a precision of 0.01 grams; adjusting the temperature of the sample to 20°C; titrating the sample with distilled water at 20 +/- 1°C while mixing thoroughly until small particles of precipitate appear on further addition of water, and result is calculated as follows: x = V ml / w g V is Volume of distilled water added (ml); w is Sample weight (g); Water tolerance ratio is 1 : x . V is Volume of distilled water added (ml); w is Sample weight (g); Water tolerance ratio is 1 : x . <EOS>
