| Zusammenfassung: | An improved hot-melt-type adhesive is improved by including in the hot-melt-type adhesive the reaction product of pine rosin with formaldehyde. The addition of the pine rosin/formaldehyde reaction product improves the separation of the adhesive from the substrate in an alkaline washing bath. The adhesive precipitates as a coarsely dispersed non tacky form and can be easily removed from the washing bath. |
